Bidim Fabric

Used as a filtration membrane to minimise and control soil and dirty water leaching through the retaining wall from behind. When combined with a good drainage cell of gravel and an appropriately sized ag pipe, it will help keep your retaining wall cleaner for longer and minimise the frequency of cleaning with a pressure washer.

Bidim fabric can be purchased either by the full 50 L/m roll or simply cut to the metre. It is available in both 1m and 2m heights to suit most wall applications.
